Welcome back! This is the sixth episode in the "C# Programming for Absolute Beginners" course. So far, we have learned about the most important features of C#, we have installed the free Visual Studio Community Edition IDE, and we have created our first Windows Forms application. Then, we have played with MessageBox controls, and we went through all the C# variables, using practical examples for each one of them.

This tutorial will discuss arrays, which are nothing more than collections of variables of the same type. So, let's create a new Windows Forms project, and then add a button to it. Then, double click the button to display the code associated to it.

Welcome! We are Layers of Meaning

We offer tutorials for beginners. Free samples are available. Check them out!

Welcome! This is the fifth episode in the "Build Your Business Online" course. So far, we have learned how to set up profitable Google AdWords campaigns. Most of the advertising world is focused on Google and their PPC advertising option (AdWords), after all.

Although Google does have the lion's share of the traffic, so it would be foolish to ignore what they have to offer, you should not ignore Bing Ads. This advertising network, which focuses on the old MSN search website (now Bing), Yahoo and AOL, allows you to reach an entirely different audience, and in many cases to do so at a lower cost than what you would spend with the Google network.

Welcome back! This is the fourth episode in the wireless networks course. So far, we have covered the way in which data is transferred over regular, wired networks, and we have understood the way in which wireless networks work.

This lesson will discuss Wi-Fi channels in great detail. We will learn how to pick the best channel for our Wi-Fi network. A hint: it's not always best to pick an unused one! Let's get started.

In an ideal world, you would be the only person using Wi-Fi in your city. However, things don't work this way. Just like the number of cars, the number of Wi-Fi networks is constantly growing each year. Data Alliance's stats show that the number of wireless hotspots worldwide will exceed 217 million in 2017.
